Addition of testing infrastructure for vector math functions.
We test vector math functions using scalar tests infrastructure with help of special wrappers from scalar versions to vector ones. Wrapper implemented using platform specific vector types and placed in separate file for compilation with architecture specific options, main part of test has no such options. With help of system of definitions unfolding of which is drived from test code we have wrapper called in individual testing function instead of scalar function. Also system of definitions includes generated during make check header math/libm-have-vector-test.h with series of conditional definitions which help to avoid build fails for functions having no vector versions; runtime architecture check to prevent runtime fails of test run on inappropriate hardware. * math/Makefile: Added rules for vector tests. * math/gen-libm-have-vector-test.sh: Added generation of wrapper declaration under condition. * math/test-double-vlen2.h: New file. * math/test-double-vlen4.h: New file. * math/test-double-vlen8.h: New file. * math/test-vec-loop.h: Added initialization macro. * sysdeps/x86_64/fpu/Makefile: Added variables for vector tests. * sysdeps/x86_64/fpu/libm-test-ulps: Regenarated. * sysdeps/x86_64/fpu/math-tests-arch.h: New file. * sysdeps/x86_64/fpu/test-double-vlen2-wrappers.c: New file. * sysdeps/x86_64/fpu/test-double-vlen2.c: New file. * sysdeps/x86_64/fpu/test-double-vlen4-avx2-wrappers.c: New file. * sysdeps/x86_64/fpu/test-double-vlen4-avx2.c: New file. * sysdeps/x86_64/fpu/test-double-vlen4-wrappers.c: New file. * sysdeps/x86_64/fpu/test-double-vlen4.c: New file. * sysdeps/x86_64/fpu/test-double-vlen8-wrappers.c: New file. * sysdeps/x86_64/fpu/test-double-vlen8.c: New file.
